is booting.

Press the Start button on the lower left-hand side of the
screen.
Type "control userpasswords2" in the text field
that appears and press "Enter."
Uncheck "Users must enter a username and password"
and restart the computer.

button and chose Control Panel from the menu that appears.

drop-down box and choose "All Control Panel Items."

OK, if you are running Windows 7, Microsoft tightened
security on it so you've got to have a password reset disk which 99% of the
people who own laptops with windows 7 fail to do. It should be one of the
first things you do when you buy the laptop. Otherwise, you're faced with
reinstalling the Operating System or possibly doing a System Recovery.

If you're on Windows XP or Vista try this:

Turn off the computer, then hit the power button to turn it back on and
immediately start hitting the F8 key repeatedly until you see the Safe Mode
option. Select SAFE MODE and let the computer boot up. When it gets
to the User Login screen it will show the Administrator userid and the userid
for which you forgot the password. Sign in as the Administrator (hopefully
you didn't put a password on it and forgot it too). Once the desktop
appears it will look different, the screen will be darker and the icons bigger,
but this is normal for safe mode.

Click Start/Control Panel/User Accounts
When the User Accounts screen opens, click on the userid for which you forgot
the password. Select the option to REMOVE PASSWORD.
